Instruction
The Rust project at /app is the source tree of quinn. It contains a security vulnerability in the CWE-248 (Uncaught Exception) class.
Audit the codebase for a vulnerability of this class. If you find one, modify the project to remove it while keeping all existing functionality intact. If you find no such vulnerability, make no changes.
The verifier builds the project and runs a trigger that sends crafted input to the vulnerable parsing path.
